(54) IMPROVEMENTS IN OR RELATING TO
HEAT/SOUND INSULATION MEANS
(71) We, HARDSTOCK LIMITED, a
British Company of Beaver House, Charlton
Road, Hitchin, Herts, SG5 2AL, England, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to shutters such as may be used for insulating window spaces in buildings against transmission of heat and/or sound.
Since relatively thin sheets of glass are used for glazing of windows compared with the wall thickness of a building, the heat and sound transmission coefficients for the window spaces are high compared with those for the walls. Furthermore, gaps may exist around the window frames which are not conductive to restricting such transmission.
According to the present invention there is provided a shutter comprising a plurality of elongate slats disposed with their longitudinal directions parallel with one another and connected with one another at their ends in such a way as to allow the shutter to adopt, when desired, an extended closed position in which the slats are arranged in a line extending perpendicular to the direction of longitudinal extent of the slats and with each slat engaging the adjoining slats closely, with the slats having their major faces facing transversely of the direction in which said line extends and with each slat engaging the adjoining slats closely, and to allow the shutter to adopt, when desired, another position in which the major faces of the slats face in the direction in which said line extends, and wherein each slat is in the form of a plank of cellular composition (as hereinafter defined), each said plank having fitted to each of its longitudinal ends a respective end cap, each said slat being connected with the or each adjacent said slat by way of connecting means attached to said end caps.
The term "of cellular composition", as used herein to refer to a plank forming a shutter slat is used to indicate that the plank is not solid but comprises, within an outer wall of the plank, a plurality of empty spaces divided off from one another by solid material.
Embodiments of the invention are described below, with reference to the accompanying, partly diagrammatic drawings, in which:
Figure 1 is a fragmentary elevation view of a shutter, embodying the invention, with only one slat shown and that slat shown with a portion broken away and sectioned, portions of an associated window frame and upper and lower tracking also being shown.

Figure 6 in a stowed position;
Figure 8 is a diagrammatic plan view of a series of slats of the shutter of Figures 6 and 7 folded in accordian fashion;
Figure 9 is a diagrammatic plan view of a series of slats of the shutter of Figures 6 to 8 in an extended closed position: and
Figure 10 is a diagrammatic plan view of a series of slats of the shutter of Figures 6 to 9 in a louvred position.
Referring to Figures 1 to 5, a shutter comprises a plurality of elongate slats disposed with their longitudinal directions vertical and thus parallel with one another, after the fashion of a vertical venetian blind.
Each slat is in the form of a plank formed of polyvinyl chloride by extrusion, and thus has a uniform cross-sectional configuration throughout its length. Each plank comprises a continuous outer wall extending around an internal space divided by internal partitions, integral with the outer wall and extending longitudinally within the plank, into a plurality of longitudinally extending cells or passages, and is thus of cellular composition, as herein defined. Each plank 2 has a central portion 4 intermediate the two opposite longitudinal edges of the plank and stepped outer portions 6 and 8 affording respective said longitudinal edges, the portion 8 carrying a longitudinally extending sealing strip 9.
Each plank 2 has fitted to its upper and its lower end a respective end cap 10, 12 respectively, having spigots extending into said cells at the respective end of the plank to retain the end cap on the plank.
The upper and lower end caps 10 and 12 respectively of each slat have each a respective pivot member, in the form of a central glider peg 14 extending longitudinally from the slat, along a longitudinal axis of the slat which is also a pivotal axis of the slat.
The series of slats forming the shutter extend between a horizontally extending, upper track 16 and a parallel lower track 18.
The tracks 16 and 18 extend between window reveals 19.
Each track 16, 18, provides a channel extending longitudinally therealong, that of the upper track being open downwardly and receiving the pegs 14 of the upper end caps 10 of all of the slats and that of the lower track being open upwardly and receiving the pegs 14 of the lower end caps 12 of all of the slats. These channels serve to guide the planks in movement in the longitudinal direction of the tracks, i.e. horizontally. Each of the end caps 10, 12 carries two pins 22, disposed on opposite sides of the pivotal axis defined by the peg 14, each pin 22 being disposed at a respective position adjoining a respective one of the two opposite longitudinal edges of the respective slat, each pin 22 extending parallel with the pivotal axis of the slat, between a respective pair of lugs 20 of the respective end cap.
The upper end caps 10 are connected by two tapes 24 each formed with pockets at regular intervals therealong, each end cap 10 having one of its pins 22 extending into a pocket in one tape and the other of its pins 22 extending into a pocket in the other tape. The lower end caps 12 are connected in an exactly analagous manner by a further two pocketed tapes.
In the preferred embodiments there are two shutters associated with the window opening, each shutter, comprising a series of slats 2 and each, in the extended position, extending from a respective one of the window reveals 19 to the middle of the window, to meet the other shutter when the latter is also in the extended position. For convenience, the slats 2 of the shutters which are closest to the respective reveals 19 are referred to below as the outermost slats and the slats of the two shutters which adjoin one another in the middle of the window when the shutters are closed are referred to as the innermost slats.
The upper and lower tracks 16, 18 are provided with end clips 26, to restrain movement of the slats 2, and centre clips 28 having resilient members 30 arranged to engage with the glider pegs 14 of the slats 2, when the shutters are in an extended position as indicated in Figure 3, 4, or 5. A locking bar 32 is positionable in clips mounted on the adjoining wall (not shown) when the shutters are in the closed position shown in
Figure 4 to give security against intruders.
As shown in Figure 2, when the shutters are not required each may be stowed, in a position in which the major faces of the slats lie flat against one another, the group of slats abutting the respective window reveal 19. To move the flights 2 to the extended position shown in Figure 3 the innermost slats are moved to engage the glider pegs 14 thereof with the resilient members 30 of the centre clips 28, the tapes 24 drawing out the remaining flights in spaced relationship. The slats 2 can then be rotated in unison about their respective pivotal axes, (rotation of one of the slats effecting rotation of the remainder by virtue of the pocketed tapes connected to each slat), to a required position, such as the closed position shown in Figure 4 or the louvred position shown in Figure 5. In the closed position since the stepped outer portion 6 of each slat overlaps the stepped outer portion 8 of the adjacent slat, the window is obturated by a lining of cellular material thereby reducing transmission of sound and heat through the window space, the sealing strips 9 enhancing sealing between adjacent slats and an end seal flange 31 secured to the reveal effecting sealing between the outermost slat and the reveal.
In the louvred position the slats are set to any desired angle to give privacy and protection from direct sunlight. Return of the slats to the stored position is achieved by rotating the slats to the position shown in
Figure 3 and then pushing the slats toward the reveal.
The shutter shown in Figures 6 to 10 has the same form as that described with reference to Figures 1 to 5, except in certain minor respects as noted below.
Thus, as in the shutter of Figures 1 to 5, the shutter of Figures 6 to 10 comprises a series of slats 32 comprising extruded planks having internal longitudinally extending cells or passages, each slat having at its upper and lower end end caps 36 and 38 respectively each having spigots engaging in the cells and each having a central glider peg 40 extending therefrom along a pivotal axis of the plank, the glider pegs, as in the embodiment of Figures 1 to 5, extending into longitudinal channels provided in horizontal parallel upper and lower tracks 42, 44, extending between window reveals 45, all as in the arrangement of Figures 1 to 5. As in the arrangement of Figures 1 to 5, each end cap 36, 38 has two pins 48 extending parallel with the pivotal axis of the slat, each pin being disposed adjacent a respective one of the two longitudinal edges of the slat and extending between a respective pair of lugs 46 of the respective end cap.
However, in the arrangement of Figures 6 to 10, each plank 32 has a resilient sealing strip 34 positioned along one of the two longitudinal edges thereof. Furthermore, adjacent slats in the arrangement of Figures 6 to 10 are connected, not by pocketed tapes, but by polypropylene links 50, each of which comprises three rigid portions hingedly connected by narrow regions each of thickness so reduced as to permit complete and repetitive flexing about a respective axis, and thus to constitute, in effect, a hinged connection between the respective rigid portions of each link 50. Each link 50 comprises, as viewed in a direction parallel with the pivotal axes of the slats, a first elongate portion comprising a straight part 52 formed with a first bearing part in the form of a half hinge knuckle 54 at one end and having at its other end a shorter leg 66 extending at right angles from the part 52 to the flexible hinged connection with a Ushaped portion 56 having parallel legs 68 connected by a base part perpendicular to legs 68. The remaining portion of each link is a second elongate portion comprising a straight part 58 formed with a half-hinge knuckle 62 at an end thereof remote from a shorter leg which extends at right angles from the part 58 to the flexible hinged connection with the U-shaped portion 56. The straight part 58 is extended in the direction away from knuckle 62 past the shorter leg of the second elongate portion, and has at its free end a further hinge knuckle 60.
The flexible connections of the two elongate portions with the U-shaped portion are between the free ends of the respective shorter legs 66 and the free ends of the arms 68 of the U-shaped portion 56. The axes of the hinges constituted by the flexible connections between the rigid portions also, of course, extend parallel with the pivotal axes of the slats.
Each link 50 consists of a first length 52 formed with a half hinge bracket 54 at one end and flanged channel section 56 at the other carrying a second length 58 formed with half hinge brackets 60, 62 at each end.
The polypropylene material adjacent arrises 64 formed between flanges 66 and arms 68 of the channel is of reduced thickness, thereby permitting complete and repetitive flexing about the arrises. Links, such as link 70, consisting of a length 72 formed with a half hinge knuckle 74 at one end and a leg 76 with a half hinge knuckle 78 at the other end, are provided at the innermost and outermost slats. A handle 80 and locking latch (not shown) are provided on the innermost slats the latch giving security against intruders.
The hinge knuckles 54, 62, 60, 74 and 78 are apertured to receive respective said pins of the slats, each series of end caps adjacent either track 42, 44 being connected by two chains of links, each half hinge knuckle 54, 62 being pivoted with a respective complementary half hinge knuckle 62, 54 or 74, 78, on a respective common said pin of a respective slat, whereby adjoining links in each said chain are pivotally connected with one another and with the slats. The links thus ensure that the slats remain parallel with one another in pivoting between a fully open, louvred position, and the closed position shown in Figure 9.
When the shutters are not required, each may be stowed, in a position in which the major faces of the slats lie flat against one another, the group of stowed slats abutting the respective window reveal 45. In this stowed position, the shutter is, in effect, folded in accordian fashion. To move the shutter to the drawn-out position shown in
Figure 8, the innermost slat is moved away from the reveal by pulling on the handle 80, the links 50 serving to draw out the remaining slats in an alternating inclined con figuration, the outermost slats 32 being restrained by end clips 82 in the tracks 16, 18. Continued movement of the innermost slat away from the reveal results in the slats taking up an aligned or closed position as shown in Figure 9, with the sealing strips 34 effecting seals between abutting slats.
When the shutter is fully extended rotation of the innermost slat effects rotation of the remaining slats in unison to a louvred position as shown in Figure 10. Return of the slats to the stored position is effected by reversing the foregoing sequence.
It will be noted that in the closed position shown in Figure 9, and in the louvred position shown in Figure 10, the straight parts 52 and 58 of each link are in alignment, with the shorter legs of the elongate portions extending from the parts 52 and 58 towards the plane of the pivotal axes of the slats, and the U-shaped members being open towards said plane. It will also be noted that the base of each U-shaped portion is set inwardly towards said plane relative to the straight portions 52 and 58, and that the portion of each straight part 58 which carries the knuckle 60 overlies part of the base of the associated U-shaped portion and the axis of the respective knuckle 60 is disposed substantially in the middle of the associated Ushaped portion.
It will also be noted that in the series of slats forming each shutter alternate slats each have each of the two pins thereof journalling the knuckle 60 of a respective link 52 in the respective chain of links,
while the other slats each have each of the
two pins thereof journalling two half
knuckles of respective links of the respective
chain.
When the shutter is in the closed position
shown in Figure 9, each U-shaped portion of each chain of links is directly opposite a
respective common pivotal connection be
tween half knuckles and a slat, and when,
from the position shown in Figure 9, the
shutter is folded in accordian fashion for
stowing, (see Figure 8) each bracket 52 flexes
about the "hinges" provided between the
elongate portions and the U-shaped portion
and the pivotal knuckle joint immediately
opposite each U-shaped portion enters the
space between the arms of the U-shaped
portion.
Whilst the foregoing description is con
cerned with two series of slats arranged to
be moved towards a central region of the
window space, it will be appreciated that a
single series of slats may be utilised to ex
tend across the whole of the window space.
